A heat pump generally refers to a device that is used to transfer heat in freezers, air conditioners and refrigerators among others. Mechanical energy is converted into thermal energy as a function of the heat pump in these machines. Refrigerants, which are fluids that are also used in the process, aid the heat pump to carry out this task. Carbon dioxide and chlorofluorocarbon are popular examples of these fluids. Different machines have different output requirement and the heat pump functions to lower temperatures or heat atmosphere as required in each case. The only purpose of a furnace on the other hand, is to provide heating. A furnace does not provide cooling. Some examples of the several sources that the furnace uses to produce heat include wood, fuel oil, natural gas, liquefied petroleum gas (LPG), coal and oil. A furnace is often found to generate heat for boilers, kilns and ovens. The heat pump is the […]
